From ESO: “Ten Years of VLT Adaptive Optics”

25 November 2011 marks the 10th anniversary of NACO, the first adaptive optics system to be installed on the ESO Very Large Telescope (VLT). NACO’s ultra-sharp vision has greatly contributed to the major discoveries made with the VLT.

“NACO, short for NAOS-CONICA, was the first adaptive optics instrument to be installed on the VLT, in 2001 (eso0137). By compensating for turbulence in the Earth’s atmosphere, NACO greatly improved the telescope’s image sharpness and scientific potential. The instrument, developed by French and German consortia with the collaboration of ESO, was the first of a series of adaptive optics instruments that would be installed on the VLT Unit Telescopes.

Adaptive optics technology has continued to evolve, and a new generation of instruments is under construction or being planned to ensure that even better facilities will be available on the VLT in future. Looking into the next decade yet more advanced adaptive optics systems are under development for ESO’s European Extremely Large Telescope, the E-ELT.”
